METAL SHEET-FILING.

SPECIFICATION forming part of Letters Patent No. 778,601, dated December27, 1904.

Application filed September 5,1903. Serial No. 172,182.

To all whom, it may concern.-

Be it known that I, GEORGE E. NYE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Metal Sheet-Piling; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to a novel construction in interlocking metalsheet-piling, the object being to provide sheet-piling which is verysimple, efficient, and durable; and it consists in the features ofconstruction and combinations of parts hereinafter fully described andclaimed.

In the accompanying drawings, illustrating my invention, Figure 1 is aplan section showing sheet-piling constructed in accordance with myinvention. Fig. 2 is a fragmentary vertical section on the line 2 2 ofFig. 1. Fig. 3 is a perspective view of a drive-foot used in connectionwith my piling. Figs. 4, 5, and 6 are horizontal sections showingvarious modifications in construction of my piling.

The essential feature of my present invention resides, mainly, in theconstruction of the interlocking unit A, which consists of two members Band 0, each of which consists of a special form of beam which issubstantially a plate having a flange D on one edge, and a rib E ofgreater depth than said flange parallel with the latter and locatedinwardly thereof, either adjacent said flange D or adjacent the otheredge of said plate, as shown in Fig. f. The said members B and C arerelatively so laid that the flange of each lies opposite the free edgeof the other, while the inner face of each member rests upon the freeedge, respectively, of the rib of the other member and is secured inthis position by means of bolts F in an obvious manner. In this manner Iprovide at each side of the pile A an L-shaped recess G, which isadapted to receive the flange and part of the web of a channel-beam H orthe flange D and adjacent portion of the web of one of the members B orO of the next adjacent pile, thereby interlocking with the latter.

Instead of the specially-rolled beams B and C angle-irons I may be used,having one leg of greater length than the other, or, in other words,said angle-irons I may be termed plates, provided along one edge with aflange J and having an angle-iron K secured to said plate inwardly ofand parallel with said flange J ,said angle-iron K being of greaterdepth than said flange, so as to provideaspace between the free edge ofone plate and the flange J of the other plate, as shown in Fig. 5. Thesame result may also be attained by the construction shown in Fig. 6, inwhich the units are each composed of two parallel plates M, each havingan angle-ironN secured to one face adjacent one edge and projectingbeyond the other face, thus forming'a flange thereon, and having asecond angle-iron O secured to the other face inwardly of the edge andforming a rib of greater depth than the flange and extending parallelwith the latter, so that said plates when bolted together in relativeposition coincide in form and function almost exactly with the units A.

It sometimes happens that sheet-piling must be driven into ground whichis more or less rocky, and there is consequently great danger ofsplitting the units, owing to the thinness of the metal. To obviatethis,I provide footpieces P, each consisting of a wedge-shaped blockprovided with a rectangular shank Q of smaller size, which is adapted tofit the openings in the units and be driven with the latter into theground, such foot-pieces beingadapted to prevent splitting of the platesand shearing of bolts of the units.

I claim as my invention 1. In metal sheet-piling, a unit composed of twomembers each consisting of a plate provided on one edge with a flangeand inwardly of said flange with a rib of greater depth than said flangeand parallel with the latter, said members being adapted to be boltedtogether so that the free edge of each overhangs the flange of theother, whereby oppositely-disposed L-shaped recesses are formed in theedges of each unit.

2. In metal sheet-piling, the combination with a plurality'of units,each composed of two members, each consisting of a plate provided on oneedge with a flange and inwardly of said flange with a rib of greaterdepth than said flange and parallel with the latter, said mem bers beingadapted to be bolted together so that the free edge of each overhangsthe flange of the other, whereby oppositely-disposed L- shaped recessesare formed in the edges of each unit, of channel-beams adapted to entersaid L-shaped recesses and interlock with said units.

3. A sheet-piling beam, comprising a web part having a right-angleflange formed on one side thereof, and a companion flange set back fromthe opposite edge and providing an overlapping web extension.

4:. In sheet-piling, companion beams rigidly secured together and havingan interi' ening space and forming a double pile-section, the web parton opposite edges of each beam extending beyond the line of theright-angle flanges bearing against the inner faces of the beams andoverlapping the corner of the joining-secti0ns when assembled in a wallstructure.

5. In sheet-piling, companion beams having flanges of difl'erent lengthsturned at right angles on opposite sides thereof, the longer flangesbeing set back from the opposite edges and providing an overlapping webextension.

6. In sheet-piling, companion beams having right-angle flanges on oneedge and longer flanges set back from the opposite edges and facinginward, and means for rigidly securing the beams together in forming awall structure.

7. In sheet-piling, companion beams having right-angle flanges turnedinward, the web part of the beams on one edge extending beyond the lineof the flanges, and the single sections having flanged edges andinterlocking with the double sections and alternating therewith whenassembled in a wall structure.

8. In sheet-piling, the combination with a double section composed ofcompanion channel-beams rigidly secured together with the channel sidesfacing inward and having recessed edges, and the single channel-beamsections interlocking with the double sections and I alternatingtherewith in a wall structure.

9. 1n sheet-piling, a corner-section consisting of companion L-beamspositioned at right angles with reference to each other and interlockingwith the double beam-sections on either side, and means for rigidlysecuring the L-beams together.

10. In sheet-piling, the combination with companion doublepiling-sections set at right angles with reference to each other inturning a corner, of a corner-section, comprising L-heams and a joiningangle-iron and interlooking with the double sections in forming acontinuous wall structure.

In testimony whereof I aflix my signature in presence of two witnesses.
